Spectrochemical Series
- The spectrochemical series is a list of ligands ordered by the field strength they exert on the central metal ion.
- Ligands that exert a stronger field cause a larger splitting of d-orbitals in the metal ion, leading to greater separation between energy levels.
- This series helps predict the color and properties of coordination complexes based on their ligands.
EXPLANATION:
- In the spectrochemical series, ligands are arranged in order of increasing field strength. Some common ligands in order are:
- \(I^- < Br^- < Cl^- < F^- < OH^- < H_2O < NH_3 < en < NO_2^- < CN^- < CO\)
- Among the provided options ( \(CN^- , Cl^- , Br^- , I^- \)):
- CN- (cyano) is the strongest ligand, exerting the greatest field strength.
The correct answer is: 1) CN^−
